A jacket is a type of sleeved hip- or waist-length garment for the upper body. For clothing older than the mid-nineteenth century, a distinction is often maintained with a coat, but in many instances the terms are now interchangeable. A jacket is generally shorter, ending just below the waist,[1] and often lighter. Some jackets are fashionable, while others serve as protective clothing.

The term comes from the French jaquette, which means either a man's morning coat or the jacket of a lady's suit.

Fleece jacket is a casual jacket made of synthetic wool such as Polar Fleece.
